would also b helpful if it allowed for more than one "correct" move rather than only the "best" move

I think most members are looking for chess.com to make improvements to tactics trainer.  It was discussed in the chat on the chess.com tv show today while Daniel Rensch was monitoring the chat.  So I think it is deffinitely something they are starting to become aware of.  The more people that chime in the better.
